项目结构

mcp-riddle/
├── server_sse.py
├── riddles.json
├── requirements.txt
├── Dockerfile
├── DEPLOY.md
└── README.md

本地运行

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python server_sse.py

启动后默认监听 0.0.0.0:8000

接口

  • SSE: GET /sse
  • MCP 消息: POST /messages
  • 健康检查: GET /health

兼容端点(用于部分第三方 Agent):

  • GET /mcp(SSE 别名)
  • POST /sse(部分平台会对同一路径发消息)
  • POST /sse/messages(SSE 消息别名)
  • POST /mcp(单路径兼容)

健康检查示例

curl http://127.0.0.1:8000/health

HTTP 模式调用示例

curl -X POST http://127.0.0.1:8000/messages \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
curl -X POST http://127.0.0.1:8000/messages \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_riddle_random","arguments":{"mode":"sequential"}}}'

Docker

docker build -t mcp-riddle .
docker run -d --name mcp-riddle-server -p 48080:8000 --restart always mcp-riddle
curl http://127.0.0.1:48080/health

AI Agent 接入

SSE 方式

{
  "mcpServers": {
    "riddle-game": {
      "url": "http://<server-ip>:48080/sse",
      "transport": "sse"
    }
  }
}

如果平台只允许填一个端点路径,优先使用 /mcp

HTTP 方式

{
  "mcpServers": {
    "riddle-game": {
      "url": "http://<server-ip>:48080/messages",
      "transport": "http"
    }
  }
}
